Previously this thirty day period, NASA’s Perseverance rover despatched in excess of the 1st audio recordings of the Martian surface, revealing the ghostly audio of Martian wind. Now, NASA has printed a recording of the rover’s generate via Mars’ Jezero Crater, offering us an idea of the racket Martians would hear if they arrived across the Perseverance rover through its journey.

In the recording, you can evidently listen to the Mars rover’s metal wheels banging across rocks and gravel, plus the creaks and squeaks of its mobility technique. There’s also a awful, significant-pitched humming seem, while the Perseverance staff isn’t sure the place that sounds is coming from. NASA says that the EDL (entry, descent, and landing) microphone was a last-moment addition to the rover and underwent small tests, so it is attainable that the mic is just buying up electromagnetic interference from the Rover because of to inappropriate shielding.

If you pay attention intently to the recording, you can hear Martians mumbling “♎︎♏︎⬧︎⧫︎❒︎□︎⍓︎ ♋︎●︎●︎ ♒︎◆︎❍︎♋︎■︎⬧︎” … that’s a joke, nevertheless I dare anyone to hear by the uncut 16-moment recording delivered by NASA. If you didn’t know it was from Mars, you could swear that a person still left their mobile phone recording when rubbing a fork against a chalkboard.

Though it definitely doesn’t audio like new music, the Perseverance rover’s recordings make its mission really feel much more personal and raise queries about the upcoming of house vacation. Mars is a actual location, included in dust, rocks, and craters that no human has at any time seen in man or woman. Yet we have recordings from the planet’s floor, and our library of recordings will keep on to improve as the Mars rover wanders about the lonely very little planet.

What to Look for in a Desktop Computer

Desktop computers give you an at home setup that’s often more powerful than a laptop and a lot easier to upgrade over the years. Purchasing a desktop PC can seem incredibly intimidating, especially if you’ve never purchased one before. Here’s everything you need to know to help you make an educated purchase decision and find the right desktop PC for you.

You might think there’s only one type of style, or “form factor” as it’s commonly called, of desktop PC—the traditional tower PC. Although that’s the most common, it’s not the only form factor. And it might not be the right form factor for you.

When thinking about which desktop type is right for you, the biggest thing you’ll need to consider is how much space you have to work with. Then, you’ll also need to decide between buying a pre-built PC and building your own.

not as complicated as it might seem. It’s a little bit like putting together pieces of a puzzle. Plus, building it yourself will save you a little bit of money.


You’ll also need to consider what you from your computer’s internals. If you want to play beefy games with beautiful graphics and no lag, you’ll need to invest in heftier, more expensive internals. If your main purpose in a desktop PC is to run work programs or use it for schoolwork, your internals don’t need to be as intense but there are still minimum requirements you should consider.

CPU has four or two cores, respectively. The more cores your CPU has, the more efficient your desktop PC will be. If you can snag at least four cores in your CPU, this is best for most people. If you need to use your desktop for gaming or any more intensive programs, you may want to invest in a CPU with more cores.
  • Windows: If you plan to use your Windows desktop PC for simple tasks for work or school, you don’t need a super powerful CPU. You should aim for a current-gen Intel Core i3 with 4 cores or an AMD Ryzen 3 processor with 4 cores. If you want a bit more power or you just want to future proof your desktop PC, you could spring for an i5, i7, Ryzen 5, or Ryzen 7. Lastly, if you mainly want a desktop PC for gaming, you should consider buying an Intel Core i9, Intel Xeon, or an AMD Ryzen 9 CPU.
  • macOS: In the future, Apple desktops will no longer be powered by Intel CPUs, but instead by Apple’s very own silicon M1 CPUs. If you’re purchasing a desktop PC from Apple, you don’t have much say over the CPU you get, but historically, Apple’s in-house CPUs have been pretty powerful. Depending on which size desktop you choose, you could either be getting the M1 CPU with 8 cores or a 10th-gen Intel i5 with 6 cores or i7 with 8 cores. Eventually, Apple will completely move away from Intel and all of its computers will be powered by its own in-house processors.
  • Chrome OS: Chromeboxes typically come with a mini PC form factor. The most common CPU brand you’ll see for Chrome OS mini PCs is Celeron. Really any CPU from Celeron is great for Chrome OS, especially if your main purpose for your desktop is simple work or school tasks. You could, however, spend a little bit more money for an Intel Core i3 or even i7 with some mini PCs.
  • Linux OS: If you want to install Linux on your desktop, follow the above recommendations for Windows OS desktops. These two operating systems function similarly with the same CPUs.
  • Although choosing your CPU is a huge decision, you’ll also need to decide on how much RAM and storage you need as well. Though the CPU is like your desktop’s brain, it still needs the right support from other components to run as smoothly as possible.

    choosing a storage option, you’ll need to choose between a hard disk drive (HDD) and a solid state drive (SSD). Let’s take a look at the pros and cons of each option:

    • HDD: An HDD can usually offer you more storage, but they’re slower than SSDs. A lot slower, in fact. But if you’re on a budget and storage is your priority, you might consider going with a larger size HDD.
    • SSD: SSDs are your best option for storage if you can afford it. They are so much faster and will help your desktop load programs at lightning speeds. You might not be able to get as much storage for an affordable price, but you’re paying for speed when you get an SSD over an HDD.

    Also, consider how much storage you want. Depending on the brand you get, HDD sizes range from lower numbers of GB, like 250 or 500, all the way up to 2, 4, even 16TB. SSD sizes are similar to HDD sizes, but you’re paying about double or more for the same storage capacity. If the computer you’re buying or building has space for two drives, you can use an SSD as your main (system) drive and an HDD for your storage drive. Then you get the speed of an SSD with the capacity of an HDD.

    GPU is referred to as an integrated GPU. For most people who are using their desktop lightly for school or work, an integrated GPU is all you need.

    If you’re a gamer or you need crisper graphics for a school or work program, consider purchasing a dedicated GPU. This is an additional internal part that would go into your computer tower to boost the graphics power.

    If you purchase a pre-built desktop PC, pay close attention to whether it comes with just a CPU or an additional dedicated GPU. If you’re custom building your PC, check out our guide on choosing and installing your GPU.


    If you think purchasing a desktop PC is over when you buy the PC, think again. There are quite a few peripherals, or extra accessories, that you’ll need to purchase to complete your experience. You may have a few of these items already, like headphones or a computer mouse, but some of these items might need to be completely new purchases for you.

    best computer monitors you can buy here.

    And you’ll also need to decide whether you want one monitor or a multi-monitor setup. Think about your desk space and how you want to use your monitors to help you decide to buy one, two, or even three monitors.

    mechanical keyboards, which will allow you to feel and hear each click and clack. There are backlit options that will help you find keys in the dark, gaming-specific keyboards, and keyboards with or without number pads on the side.

    Then, you can also decide between a Bluetooth, wireless, and wired keyboards.

    Don’t just buy the cheapest keyboard you can find on Amazon. Take your time to do a little research because you’ll be spending a lot of time typing on your keyboard. And trust me, you can feel the difference between a cheap keyboard and a quality one.

    quality computer mouse. Although there are a lot of subtle differences between computer mice, you’ll mainly be making your decision between a Bluetooth, USB-wired, and USB-wireless mouse.

    There are so many niche options for computer mice, including great ergonomic options and mice that are specifically great for gaming.

    quality microphone is essential.

    If virtual meetings are going to be essential for you, you should also invest in a quality webcam.

    a monitor stand. Monitor stands lift your monitor to a more ergonomic height to reduce eye and neck strain, while also giving you more storage space.

    There are different materials to choose from, like metal, wood, and glass, as well as different styles like a dual monitor stand or a monitor stand with extra storage. You can’t really go wrong with choosing a monitor stand, as long as you measure your desk beforehand to make sure it’ll fit.


    Another major consideration when making your desktop PC purchase is the available ports. You need to make sure it has enough ports for everything you want to connect to it for your perfect desk setup. Plus, you’ll also need to make sure all your peripherals are compatible with the available ports on your PC tower.

    Wi-Fi has improved significantly over the years. So if you’re not able to reach an Ethernet port from your desktop set up, don’t worry. You will, however, need to make sure there’s a Wi-Fi card inside your desktop to allow you to connect wirelessly to your Wi-Fi router.

    few different types of USB ports, though the most common ones you’ll see on a desktop PC are USB-A and USB-C.

    USB-A ports include USB 2.0 and USB 3.2 ports; you typically use these ports to plug in your keyboard, a wireless mouse, a microphone, or other peripherals. Depending on how advanced your peripherals are, they may have a USB-C port connection.

    Just make sure that the desktop PC you purchase has enough ports to connect everything you want to.

    While that’s a lot to consider, hopefully you have a better understanding of what sort of things to look for when purchasing a new desktop computer.
